Re: Custom Gearbox Without Automated Machining?

It really depends on the tools you have.
What will you use for the bearing holes? In a CNC you would use something like a 1/4'' endmill. Using that i doubt you can get good results with a manual mill.
If you have a good enough way to make nice 1.125'' holes, i'd think that you should be ok.
With that said, remember to add the 0.003'' to the distances of the pitch diameters for smoother runs in your gear. We recently learned that lesson the hard way.
